In 2006 I described a new species of Monodora: M. hastipetala. This species was only known from a single locality: The Matumbi Hills in Tanzania. It is a beautiful and delicate species. Though it was locally abundant in the Hills, it was still assessed as Critically Endangered by the IUCN Species Survival Commission Eastern Africa Plant Red List Authority chaired by Quentin Luke.
Monodora hastipetala Couvreur:
Recently, Roy Gereau contacted me about a "mystery Monodora" from Southern Tanzania. I was very excited to see that it was in fact M. hastipetala, although with some differences in size of petals. This changed the IUCN status from CR to Endangered!
This is great news for one of the most beautiful genera in Annonaceae: no more critically endangered species!
This really underlines that IUCN assessments are very dynamic.
